In literature the determination of the contact ratio of crossed helical gear pairs is presented up to now only in general form. Especially under consideration of the relatively large tolerances occurring in mass production calculation measures needed for the design are lacking which consider the ...
This model also leads to the distribution of the tooth bending stress and the contact stress along the area of contact. 展开 关键词: Helical gears Gear load distribution Plastic gears Stress calculation DOI: 10.1016/j.mechmachtheory.2009.07.003 被引量: 17 ...
This paper proposes new formulae for estimating the coefficient of friction at rolling-sliding contact surfaces under a mixed lubrication condition. The lubrication condition is expressed as a function of the ratio of the maximum height ... S Matsumoto,K Morikawa - 《International Gear Conference –...
used RE to redesign and optimize the gear ratio and corresponding teeth number of the gears of an automatic transmission system. They proposed an accurate and efficient model to find optimum design parameters [11]. Verim et al. redesigned a damaged motor cam gear by the 3D scanning method. ...

Introduction The application of helical gears can be found in planetary gear trains for turbine gearboxes [1], wave energy converters [2] and automobiles [3], to cite only...
vibration under lighter loading condition. The results showed that the partial contact loss due to gear errors in light loading condition has significant effect on system vibration. Munro et al. [10] presented an approximate formula of transmission error considering corner contact due to manufacturing...

The relation between contact ratio and stiffness function is presented. A comparative study has been performed to investigate the effect of the total contact ratio and its components on the dynamic characterisrics of helical gear pairs.Virgil ATANASIU...
In further study we find the effect of coefficient of asymmetry on contact ratio of helical gear pairs, here it shows that decreased in coefficient of asymmetry leads to increased contact ratio.doi:10.32628/IJSRSET173135Shivaji V. GawaliHarshal P. Rahate...
